This rig is from a company called RG Petro-Machinery, whose ironic slogan is "humanism above all." A workover rig, as opposed to a drill rig, is used to support drilling operations like pulling pipe and sealing wells. This monster can be equipped to traverse deserts in Central Asia or swamps in South America and features a Cat engine paired with an Allison transmission.
